America will celebrate its 50th anniversary by releasing a career-spanning eight-disc box set titled Half Century in early June that features a treasure trove of unreleased audio and video.

The collection boasts seven CDs featuring rare alternate mixes, demos, rehearsals, live performances and interviews, plus a DVD featuring “home movies” of the band filmed from 1972 to 1975.

Disc 1 is called London Demos 1970, and features unreleased demos recorded in various London studios the year before America’s self-titled debut was released. It includes early versions of four tunes that appeared on America, plus other songs.

Disc 2, titled Bremen 1973 (Live on Air), features newly mixed audio of a show that the band played in Bremen, Germany, which previously was available only on DVD.

Disc 3, dubbed The Caribou Sessions 1976, features previously unreleased rehearsals, outtakes and demos recorded in February 1976 during the making of America’s 1976 album, Hideaway.

Disc 4 is called The Poison Oak Sessions 1981, and contains tracks recorded at Dewey Bunnell‘s home studio in Northern California, including unheard songs and early versions of tunes that would appear on later America albums.

Disc 5, titled The Alternate 90’s, features alternate mixes of songs from two albums, 1994’s Hourglass and 1998’s Human Nature, as well as unreleased tunes recorded before, during and after those records.

Discs 6 and 7 feature various radio interviews with America spanning from 1974 into the 2000s

The final disc, which will only be available on the box set, is the Home Movies DVD, which offers “fly on the wall” footage of the band, including behind-the-scenes segments of America making the 1973 album Hat Trick, early attempts at music videos and scenes from the road.
